I wanted to ask , about the letter "noon" that Gunna is one of its characteristics. When we read the first ayah of surah al Qalam i.e "NOOOOOON", will there still be a gunna when saying it? As beacause, when we write noon in arabic it'll have three letters in it. The first wil be a "noon" "wow" and a "noon" . The middle of the three is a medd letter which is not supposed to have a gunna.so will this letter/ayah have a gunna in it when reading. or will it have a gunna partially in it?
Jazaki Allah U Khairan

Answer
Wa alaikum assalaam wa rahmatullahi wa barakaatuh,
The ghunnah is an inherent characteristic of the whether it is voweled or saakinah. If you close your nostrils, you will not be able to say the properly, since you are eliminating the ghunnah when you do that. This doesn't mean the ghunnah is prolonged in every , instead it means there is a nasal component of the , and that component is always there.
In aayah 1 of surah Al-Qalam, the will have its inherent ghunnah (you can test this by closing your nostrils and noting the sound is cut off), but the in between the two should not have a ghunnah, and if you close your nostrils while lengthening the for the six vowel counts it is lengthened here, you should hear a clear sound, and not an imprisoned sound or partially cut off sound.
